With EVE Online turning six years-old today and surpassing the 300,000 active subscriber mark over the past few days, there was really only one way for developer CCP to celebrate - spaceship cake.

While other massively multiplayer online games have drawn huge numbers and then struggled to retain them, CCP's EVE Online has spent the past six years growing. So far 2009 has been very good to the game, with the concurrent user record being broken three separate times so far, with a standing record of 53,850 online at one time in one universe. The launch of the latest expansion, Apocrypha, has drawn even more players to the game, with active subscribers passing the 300K mark in the past week. Having started off the year with approximately 244,000, that's a 22% growth - for a six year-old game.

Along with the announcement, CCP sent along this picture of the celebration cake they enjoyed at their North American headquarters in Atlanta. I'd congratulate them, but they know I live in Atlanta and neglected to invite me over for gamecake, a transgression I'm afraid I can never forgive. Check out their full announcement below, while I curl up on the couch with a Little Debbie Swiss cake roll and cry.

EVE Online celebrates its 6th year of existence today—May 6th. That's six strong years of continuous growth thanks to tireless integration of user feedback into game design and pushing to release around two major free expansions per year. Our single-shard world, where everyone plays on the same shared server, has seen tremendous benefit from having each player able to interact and affect each other player in a persistent manner. From massive fleet battles to individual bonds of trust, every pilot in EVE has the potential to rock the ship of hundreds of thousands of others by their actions.

At one population milestone we saw agreements form between alliances. At another we were able to fully turn over the economy to the players. As the population of New Eden has grown, so have the instances of emergent behaviors of its pilots. A 6 year persistant history. A living history where truly brilliant strategies have unfolded. Truly terrible betrayals unveiled. We are excited to see what will happen next.

This year has been very successful for EVE Online, thanks in large part to our latest free expansion EVE Online: Apocrypha and a return to retail. We started out the year with around 244,000 subscribers and in five short months we've had a 22% growth in subscribers. In the past couple days we surpassed the impressive milestone of 300,000 active subscribers. That doesn't include trial accounts. We've broken our peak concurrent user record 3 times this year alone, standing now at an impressive 53,850 in the same universe. That is exponential growth. We couldn't think of a better birthday present than having more people playing EVE Online than ever before. It is another sweet reminder of EVE's boundless potential.

As always, we encourage you to bring your friends, family and even enemies to New Eden by visiting www.eveonline.com and downloading a free trial or by heading to your local retailer and purchasing a copy of EVE Online, which includes 60 days of game time.
